Mathematical analysis of the buttress dam under thermal impacts as part of the precipitation flow regulation system

XXI century is age of fresh water shortage. An increasing number of cities and whole regions experience the shortage of this resource. The Peninsula of Crimea and many cities on the Black Sea coast are in shortage of water iun the summer-autumn period. The lack of this resource restrains the development of tourism, agriculture, industry. Absolutely new technological and technical decisions are developed in the Kuban State Agrarian University, namely systems of atmospheric prercipitations flow adjustment, allowing providing water for both population and production. The systems may consist of both only underground storage pools, and include underground and above-ground storage pools, that allow collecting the considerable volumes of fresh water, in the limited space of mountain canyons. This system implies construction of complex hydrotechnical buildings. At present realization of this task became possible in connection with creation of modern hydraulic insulating materials, eliminating the loss of the accumulated water, and modern methods of engineerings calculations, underground and above-ground buildings, allowing the unique solution of the problem of reliability and safety of objects. At the same time making calculations it was established that the regulatory sources do not consider the factors which render meaningful influence on safe exploitation of difficult hydro-technical buildings. One of such factors is the uneven temperature loading. In the article the question of influence of the temperature loading is comprehensively considered on the area of basic structural elements reenforcement of part of the atmospheric precipitations flow adjusting system, namely buttress reinforced-concrete dam, such as a vertical pressure verge, buttresses and grillage. The obtained results allowed comprehensively analyzing the work of buttress reinforced concrete dam and carry out a deeper research of the temperature load influence.
Keywords: Atmospheric precipitations flow adjusting system, fresh water, dam, hydrotechnical buildings, mathematical design, uneven temperature loadings, tensely deformed state
